Use of Internal Hard Disk Drives in the RAID System
This section describes how to use the internal hard disk drives in the RAID System.
Important If you use hard disk drives in the RAID System or change the RAID level,
initialize the hard disk drives. If the hard disk drive contains valuable data,
be sure to backup the hard disk drive before installing the RAID Controller
and configuring the RAID System.
Note
In the RAID System, use hard disk drives that have the same specifications
(capacity, rotational speed, and standard) for each Disk Array.
Tips
Logical Drives can be created even with only one Physical Device.
To build a RAID System, There is a way to use a Option RAID controller(N8103-149/150/151) in addition to
the way to use on-board RAID Controller(LSI Embedded MegaRAID
TM
).
If using internal hard disk drives in RAID System with an optional RAID Controller (N8103-149/150/151)
installed in the server, the SATA cable needs to be rewired.
Tips
When using SAS hard disk drives, RAID Controllers must be connected.
To build a RAID System, change jumper switch settings on motherboard, as shown below.
Important You must avoid static electricity to work with the procedure below. For
details, refer to Chapter 2 (1.2 Anti-static Measures).
To use onboard RAID Controller, change setting of RAID configuration jumper on motherboard.
Warning: If [RAID_key1] has been set to [Enabled] in MB before replacement and that parameter on MB
after replacement is set to [Disabled], booting the server will destroy the data.
